TRENTON — Gov. Chris Christie had an extra set of cameras capturing the stroll from his office to Assembly chambers for today's joint session.

Turns out a crew from ABC News was filming material to go with an interview Jake Tapper taped with the sought-after Republican governor, said Maria Comella, Christie's deputy chief of staff for communications. The Nightline sit-down is set to air Tuesday.

The senior White House correspondent tweeted a picture of himself getting ready for their talk and some images from the governor's outer office, including the portraits of past governors.
